managed to get the Game Capture HD60’s video into OBS on macOS(!) via a local RTMP repeater (custom minimal build of nginx with the rtmp plugin)
delay is… a whole fucken lot, sadly https://awoo.space/media/jJ33bN1Kn5WD_7DfIQ0
FUNNILY ENOUGH passing a raw H.264 stream between three applications without touching it is less CPU intensive than putting it in the desktop compositor, capturing and then recompressing it WHO WOULD HAVE THOUGHT
I believe most of the delay can be mitigated by configuration changes in the apps involved, I just haven’t done much more than package up a Homebrew formula for the minimal build of Nginx preconfigured with the RTMP add-on (will share soon)
